Central Bank, Central Bank Intervention, Foreign Exchange Rate
The paper tried to establish whether central bank intervention could reduce exchange rate volatility by stopping speculative attacks against a currency. The author's concern centered on the fact that exchange rate volatility has increased since the adoption of flexible exchange rate system in 1973 and the subsequent interventions by most central banks. She observed that many European countries have intervened in foreign exchange markets when deemed necessary to reduce volatility and possibly keep exchange rates within a band around a target rate. But opinions still differ on whether these interventions could stabilize exchange rates. The paper, therefore, sought to present empirical evidence suggesting that central bank intervention does not generally reduce exchange rate volatility but appears strongly to have had minimal effect on volatility. This it did by using "implied volatility" to measure exchange rate volatility through the estimation of a model that relates changes in volatility to central bank intervention and other economic variables.
